556UW Universal Transponder Bypass

556UW-i  Universal Transponder Bypass

IMPORTANT NOTE:  It is almost certain you will need to use one of your "chipped" keys to complete your remote start installation using this module.  Consequently, you will need  TWO (2) chipped keys at the time of installation - One to be incorporated with this device, and the other for running your car.  If you don't have a second chipped key besides the one with which you drive your car, you will need to obtain one prior to installing your remote start unit.  Therefore, you might want to check the application guide to see if there is an "XK" model avail for your vehicle.  Although the XK units cost about $20 more, duplicating chipped keys usually runs between $70 & $100

Universal Transponder Bypass  

Overview: The 556UW immobilizer interface module is used when installing remote start products (sold separately) in select vehicles equipped with an RF (Radio Frequency) based immobilizer system. This type of system uses a small chip imbedded in the ignition key, called a transponder, to transmit a very low powered RF signal. This signal is picked up through an antenna (or coil) around the ignition switch which is then sent to the immobilizer's transceiver. Once the correct signal is received, the immobilizer will enable the ignition and/or fuel systems. If an attempt is made to start the vehicle and the transceiver does not receive a valid code, the ignition and sometimes the fuel systems are disabled. The immobilizer system will then render the remote start useless. The 556U bypasses the immobilizer system only while the remote start is in use, maintaining the factory system's integrity. When the remote start system is not in use the factory immobilizer remains fully functional

Allows remote start in vehicles equipped with a transponder or radio-frequency based immobilizer

556UW-i  Universal Transponder Bypass

Bypass Essentials modules work with your vehicle's anti-theft system to incorporate the convenience, security and luxury features of your alarm system.

Universal bypass modules work with any vehicle using an "immobilizer" key system, allowing you to remote start your car without disrupting factory-installed anti-theft features.

Use the 556U universal bypass in vehicles equipped with a transponder or RF-based immobilizer, such as those found in many late-model GM vehicles. The compact module is tunable for European or domestic vehicles and features tamper-resistant circuitry.

Important Note: One of your car's transponder keys will be permanently installed in the 556U module. You can buy an extra key through your dealer and have it programmed to work with your car's immobilizer. Ask your dealer if keys can be programmed individually — some vehicle manufacturers require that all keys be reprogrammed at one time.
